You are right, when similar objects textbox like name of customer and salary i have the problem that setall("inputmask","999,999,999.99","textbox") do you know some way to identify when textbox is using really number and not text? some different like do my own textbox class because i'm trying to do not have to change every textbox in several forms...

thanks
